Abstract: The present high pressure mechanical seal features a novel configuration capable of sealing from one up to simultaneously five power conduction lines, flow injection lines or control lines, in the same device. Adaptable to different configurations, types and size of conduction lines existing in the industry. The power conduction lines can be a cable of an electro-submersible pump or the cable in a down hole heater; the flow and control lines can be diluents injector capillaries or data and instrumentation cables or any other type of conduction line which can enter the inner atmosphere of the wellbore. Conduction lines are generally shaped as uniform cylindrical elements, which vary in diameter and material due to the cylindrical geometry, are adaptable to the sealing system of the present invention, such that the equipment can seal from only one line up to five lines depending on the requirement of the user.
